CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is related to and claims priority from prior provisional application No. 62/361,507, filed on Jul. 13, 2016.

TECHNICAL FIELD OF THE INVENTION

The present patent application pertains generally to a smart lighting system, and specifically to a smart lighting system for a two-wheeled vehicle like a bicycle.

BACKGROUND

Over the recent times, there has been a substantial increase in the adoption and use of bicycles for various purposes varying from being a mode of commutation to mode of recreation. However, unlike the other vehicles like cars and motorcycles, the safety of the rider of the bicycles is compromised, mainly due to the challenges in providing an effective lighting system. The lack of proper lighting system compromises the safety of the riders due to two reasons. Firstly, the rider of the bicycle is unable to see clearly the path and any approaching vehicle traffic and animals on the roads. Secondly, the bicycle and the rider of the bicycle may not be clearly observable to the users of the other vehicles on the roads, thereby making the bicycle and the rider of the bicycle susceptible to collisions with other vehicles thereby causing accidents. It has been seen that the lack of proper lighting in the bicycles is the major cause of bicycle-related accidents in the dark.

Bicycles may be provided with certain lighting solutions which may be powered by a battery carried on the bicycle or by dynamo generating electricity using the kinetic energy of the moving bicycle. However, generally such arrangements involve extensive electrical wiring. Such wiring may pose problems for the rider of the bicycle during riding the bicycle. Further, such wiring could also badly affect the aesthetic appeal of the bicycle.

Therefore, an improved lighting solution is desired for bicycles that can afford safety to the rider of bicycles as well as help in preventing bicycle-related accidents.

DETAILED DESCRIPTION

A smart lighting system, particularly for two-wheeled vehicle like bicycles, is described. The smart lighting system includes a lighting assembly which further includes at least one light source. The lighting assembly is mounted on the bicycle. The lighting assembly is preferably mounted at the front end of the bicycle preferably on the handle of the bicycle.

The lighting assembly of the smart lighting system communicates with a signal generator to receive signals to control the lighting produced by the lighting assembly. In one embodiment, the signal generator is a motion sensor mounted on a helmet of a rider riding the bicycle. The rider of the bicycle may control the lighting provided by the lighting assembly by performing certain gestures by his head. The motion sensor mounted on the head of the rider detects the gesture performed and based on the gesture a signal is generated to further effect a change in the direction of the projection of the lighting produced by the lighting assembly.

The lighting assembly includes a rotatable lighting source provided with a rotor. The rotor is driven by an electric motor. Based on the signal received from the signal generator, the rotor rotates the rotating lighting source to thereby change the orientation of the rotating lighting source. For example, the motion sensor may detect the gesture of head of the rider moving up and down. Based on the movement of the head, the motion sensor generates a signal to cause the movement of the rotatable light source to an extent and speed corresponding to the movement of the head of the rider so that the light beam projection is always in line with the direction in which eyes of the rider are pointing.

The lighting assembly further includes a left indicator light and a right indictor light. The left indicator light and the right indictor light are activated to project light on the left and right side of the bicycle based on which side the bicycle is turning. The motion sensor may detect the gesture of head of the rider moving sideways to the left or the right side. Based on the movement of the head, the motion sensor generates a signal to cause activation of either the left indicator light or the right indictor light.

The rotatable lighting source, the left indicator light and the right indictor light may communicate with the motion sensor through wireless means such as Bluetooth and Wi-Fi.

The lighting assembly of the smart lighting system is mounted on a front end of the bicycle. Further, the smart lighting system includes a signal receiver. The signal receiver receives signals through Bluetooth or Wi-Fi from a signal generator. The signal generator may be provided on the helmet of the rider of the bicycle. The helmet further includes a motion sensor. The signal generator communicates with the motion sensor, and based on the sensing of the motion sensor, generates a signal. Upon receiving the signal generated by the signal generator, the signal receiver passes the signal to the lighting assembly.

Thus, the lighting assembly includes the rotatable lighting source, and the left indicator light and the right indictor light. Based on the signal received, the rotatable light source is rotated so that light beam projection by the rotatable lighting source is always in line with the direction in which eyes of the rider are pointing.

Further, based on the signal received, the left indicator light or the right indictor light is activated to project light on the ground on the left or the right side of bicycle, thereby providing indication to the other commuters on the road about the intention of the rider of the bicycle of turning in either the left or the right direction, as well as illuminating the path for rider of the bicycle in the left or the right side.

The smart lighting system, therefore, provides the advantages of providing a convenient way of changing the orientation of the rotatable lighting source, such that the rider can change the orientation of the rotatable lighting source merely by the movement of the head. Also, the light produced by the rotatable lighting source is projected more accurately in the direction the rider is looking, thereby improving visibility for the rider in the dark, thereby reducing chances of accidents. Further, the smart lighting system provides for easy and convenient way of giving indication by activating the left indicator light and the right indicator light merely by movement of the head of the rider. Further, by projecting the light of the left indicator light and the right indicator light on the ground, the smart lighting system improves visibility of the rider of the bicycle on the left and right sides, as well as makes the rider as well as the bicycle more observable on the road, thereby reducing chances of accidents.

FIG. 1 depicts a top view of the lighting stem assembly 001. As it can be seen, the lighting stem assembly 001 includes a rotatable lighting source 002. The lighting stem assembly 001 further includes the left indicator light 007 a and the right indictor light 007 b. The lighting stem assembly 001 also includes a control panel 003.

In an embodiment, the rotatable lighting source 002 is provided on the front end of the lighting stem assembly 001, such that upon the activation of the rotatable lighting source 002, the light produced by the rotatable lighting source 002 is projected ahead of the rider riding the bicycle. As mentioned earlier, the rotatable lighting source 002 is rotatable to change the orientation of the light produced by the rotatable lighting source 002. For example, the rotatable lighting source 002 is oriented downwards to project light and illuminate the region nearer to the bicycle. The rotatable lighting source 002 may be oriented to upwards to project light and illuminate region farther away from the bicycle.

The left indicator light 007 a and the right indictor light 007 b are provided along the two longitudinal sides of the lighting stem assembly 001. The left indicator light 007 a and the right indictor light 007 b are provided at the bottom of the lighting stem assembly 001, so that when activated, the light produced by the left indicator light 007 a and the right indictor light 007 b is projected on the road.

The lighting stem assembly 001 further includes a control panel 003. The control panel 003 is provided on the top of the lighting stem assembly 001. The control panel may include a display screen to provide information about the various parameters associated with the bicycle, such as speed, slope, time, battery status. Further, the control panel may include control switches for controlling the various components.

FIG. 2 depicts a right-side view of the lighting stem assembly 001. As it can be seen in FIG. 2, the lighting stem assembly 001 includes the rotatable lighting source 002 provided on the front end of the lighting stem assembly 001, the left and right indicator lights 007 provided at the bottom of the lighting stem assembly 001, and the control panel 003 provided on the top of the lighting stem assembly 001.

FIG. 3 depicts a left side view of the lighting stem assembly 001. As it can be seen in FIG. 2, the lighting stem assembly 001 includes a power socket 009. The power socket 009 can be used for powering and charging various electronic devices, such as mobile phones. In an embodiment, the power socket 009 is a USB port. The power socket 009 can be provided at any suitable location on the lighting stem assembly 001. For example, the power socket 009 can be provided on one of the longitudinal vertical surface of the lighting stem assembly 001, as shown in the FIG. 3.

FIG. 4 shows a top view of the lighting stem assembly 001. The FIG. 4 shows a display screen 010 of the control panel of the lighting stem assembly 001. As mentioned earlier, the control panel includes the display screen 010 to display information about the various parameters associated with the bicycle, such as speed, slope, time, battery status. The display screen 010 is provided on the top surface of the lighting stem assembly 001 for easy viewing and accessing by the rider of the bicycle. In an embodiment, the display screen 010 is a touch-enabled screen.

FIG. 5 shows a bottom view of the lighting stem assembly 001. It can be seen that the rotatable lighting source 002 is provided on the front end of the lighting stem assembly 001, such that upon activation of the rotatable lighting source 002, the light produced by the rotatable lighting source 002 is projected ahead of the rider riding the bicycle. Further, the lighting stem assembly 001 includes a window which allows the rotatable lighting source 002 to rotate so that the orientation of the rotatable lighting source 002 and the light produced by the rotatable lighting source 002 can be changed.

Further, FIG. 5 shows the left indicator light 007 a and the right indictor light 007 b provided along the two longitudinal sides of the lighting stem assembly 001 at the bottom of the lighting stem assembly 001. Upon activation, the light produced by the left indicator light 007 a and the right indictor light 007 b is projected on the road.

FIG. 6 shows a perspective view of the lighting stem assembly 001. It can be seen that the rotatable lighting source 002 is provided on the front end of the lighting stem assembly 001. Further, the lighting stem assembly 001 includes a window out of which the rotatable lighting source 002 heads out. The window is kept large in size to allow rotation of the rotatable lighting source 002 so that the orientation of the rotatable lighting source 002 and the light produced by the rotatable lighting source 002 can be changed. Upon activation of the rotatable lighting source 002, the light produced by the rotatable lighting source 002 is projected ahead of the rider riding the bicycle. The rotatable lighting source 002 may rotate about a horizontal axis, as shown in the FIG. 6. Further, FIG. 6 shows the rotatable lighting source 002 oriented more upwards along the horizontal plane. In this orientation, the rotatable lighting source 002 projects light and illuminate region farther away from the bicycle, thereby providing a long-range illumination.

FIG. 7 shows a perspective view of the lighting stem assembly 001 with the rotatable lighting source 002 positioned in a different orientation. As mentioned earlier, the rotatable lighting source 002 may rotate about a horizontal axis, as shown in the FIG. 7. Further, FIG. 7 shows the rotatable lighting source 002 oriented downwards more along the vertical plane. In this orientation, the rotatable lighting source 002 projects light and illuminate region nearer to the bicycle, thereby providing a short-range illumination. Thus, as the rotatable lighting source 002 rotates clockwise, the rotatable lighting source 002 is inclined more along the horizontal plane to project light and illuminate region farther away from the bicycle. On the other hand, as the rotatable lighting source 002 rotates anti-clockwise, the rotatable lighting source 002 is inclined more along the vertical plane to project light and illuminate region nearer to the bicycle.

FIG. 8 shows a cross-section view of the lighting stem assembly 001. Various constituent components of the lighting stem assembly 001 can be seen in the FIG. 8. The lighting stem assembly 001 includes a rotor 004. The rotor 004 is coupled to the rotatable lighting source 002 and is responsible for causing the rotation of the rotatable lighting source 002. The rotor 004 rotates the rotatable lighting source 002 depending upon the extent of rotation the rotatable lighting source 002 is required to undergo.

FIG. 8 further shows a motor 006. The motor 006 powers the rotor 004. In an embodiment, the motor 006 is a direct current (DC) motor powered by a DC source, such as battery. The motor 006 is coupled to the rotor 004 to drive the rotor to provide rotational motion to the rotatable lighting source 002. FIG. 8 shows the rotor 004 in a first position. Further, the left and right indicator lights 007 of the lighting stem assembly 001 can be seen in the FIG. 8. Also, the FIG. 8 shows a power socket 009, such as a USB port of the lighting stem assembly 001.

FIG. 9 shows the rotor 004 of the lighting stem assembly 001 in a second position after the rotor has undergone rotation. As mentioned earlier, the motor 006 powers the rotor 004 to drive the rotor 004 to further provide rotational motion to the rotatable lighting source. Depending upon the desired angle of the rotatable lighting source 002, the motor may cause the rotor 004 to rotate to a specific extent.

FIG. 10 shows another cross section view of the lighting stem assembly 001. In the cross-section view, the rotatable lighting source 002 and the motor 006 can be seen. Further, FIG. 10 shows the left and right indicator lights 007 of the lighting stem assembly 001. Furthermore, the FIG. 10 shows a battery 008 mounted in the lighting stem assembly 001. The battery 008 is provided to power the various components, such as rotatable lighting source 002, the left indicator light 007 a and the right indictor light 007 b, the power socket 009, and the display screen 010. Further, the battery 008 is removable mounted in the lighting stem assembly 001, such that the battery 008 may be removed and replaced, as required.

FIG. 10 also shows a light control printed circuit board (PCB) module 005. The light control PCB module 005 further includes a processor for controlling the lighting operation of the lighting stem assembly 001. The controlling of the lighting stem assembly 001 by the light control PCB module 005 is explained later in the application.

FIG. 11 shows a perspective view of the lighting stem assembly 001 with the removable parts of the lighting stem assembly 001 disassembled from each other. It can be seen that the battery 008 is mounted inside the lighting stem assembly 001 under the top surface of the lighting stem assembly 001. Further, the battery 008 may be removed by lifting the top surface of the lighting stem assembly 001.

Further, the rotatable lighting source 002 is fitted inside the lighting stem assembly 001, and which may be removed by unscrewing screws. Furthermore, the control panel 003 is provided on the top surface of the lighting stem assembly 001. Therefore, to access the battery 008, first, the control panel 003 may be required to disassembled and separated.

FIG. 12 is another perspective view of the lighting stem assembly 001 showing the removable parts of the lighting stem assembly 001 disassembled from each other. It can be seen that the lighting stem assembly 001 includes the rotatable lighting source 002 fitted inside the lighting stem assembly 001, the battery 008 mounted under the top surface of the lighting stem assembly 001, and the control panel 003 provided on the top surface of the lighting stem assembly 001. Furthermore, the FIG. 12 shows the power socket 009.

FIG. 13 shows a right-side view of the lighting stem assembly 001 showing the components disassembled from each other. FIG. 13 shows the rotatable lighting source 002, the control panel 003, the rotor 004 powering the rotatable lighting source 002, the light control PCB module 005, the motor 006 coupled to the rotor 004, the left indicator and the right indictor 007, and the battery 008. All the above-mentioned components can be disassembled for each other.

FIG. 14 shows a front view of the lighting stem assembly 001 showing the various components disassembled from each other. Starting from rear end of the lighting stem assembly 001, the lighting stem assembly 001 includes the motor 006, the left and right indicator lights 007, the rotor 004, the rotatable lighting source 002, and the control panel 003.

FIG. 15 shows a motion sensor 200. The motion sensor, as mentioned before, in one embodiment, detects the gestures performed by the rider of the bicycle using their head. For example, the gesture may include the head of the rider moving up and down. Based on the said movement of the head, the motion sensor 200 generates a signal which may be used to cause the movement of the rotatable light source 002. In another example, the gesture performed using the head of the rider includes moving the head sideways to the left or to the right side. Based on the sideways movement of the head, the motion sensor then generates a signal to cause activation of either the left indicator light or the right indictor light.

As it can be seen, the motion sensor 200 may have a curved shape. The curved shape of the motion sensor 200 allows the motion sensor 200 to be easily mounted onto the helmet of the rider.

FIG. 16 shows a perspective view of a remote control 300. The remote control 300 may be used for controlling the operation of the rotatable lighting source 002, and the left indicator light 007 a and the right indictor light 007 b. For example, the remote control 300 may be used to control the orientation and the upwards and downwards rotation of the rotatable lighting source 002, and the activation and deactivation of the left indicator light 007 a and the right indictor light 007 b. The remote control 300 may be used when the motion sensor 200 is not in use. Using the Remote Control 300, the rider can control the lighting stem assembly 001 manually by one click or touch.

FIG. 17 shows a perspective view of a Smartphone 400. The Smartphone 400 may be used for configuring and controlling the orientation and the upwards and downwards rotation of the rotatable lighting source 002, and the activation and deactivation of the left indicator light 007 a and the right indictor light 007 b when the motion sensor 200 is not in use.

FIG. 18 shows an example of a smart lighting system implemented on a bicycle and a bicycle rider. The lighting stem assembly 001 of the smart lighting system is mounted on the bicycle. The lighting stem assembly 001 further includes signal generator 011 mounted on the helmet 014 of the rider of the bicycle 013. The signal generator 011 could be a motion sensor 200. The lighting stem assembly 001, as explained earlier, includes signal receiver 012 communicating with the motion sensor 200 over a wireless connection like Bluetooth and Wi-Fi.

During working of the smart lighting system, the motion sensor 200 detects gesture performed using head of the rider of the bicycle 013 for controlling the various lightings like rotatable lighting source 002, and the left indicator light 007 a and the right indictor light 007 b. Corresponding to the gesture detected by the motion sensor 200, the signal generator 011 generates a signal to be received by the signal receiver 012.

The signal receiver 012 is mounted on the lighting stem assembly 001. Upon receiving the signal generated by the signal generator 011, the signal receiver 012 passes the signal to the light control PCB module 005. The light control PCB module 005 is further connected to the various lightings like rotatable lighting source 002, and the left indicator light 007 a and the right indictor light 007 b.

For example, the motion sensor 200 may detect the gesture of head of the rider moving up and down. Based on the gesture as detected by the motion sensor 200, the signal generator 011 generates a signal to cause the movement of the rotatable lighting source 002 to an extent and speed corresponding to the movement of the head of the rider so that the light beam projection is always in line with the direction in which eyes of the rider are pointing. The signal generated by the signal generator 011 is received by the signal receiver 012. The signal received by the signal receiver 012 is then passed on to the light control PCB module 005. The light control PCB module 005 then communicates with the motor 006 to activate the motor 006. The motor 006 further powers rotor 004. The rotor is coupled to the rotatable lighting source 002 and causes rotation of the rotatable lighting source 002 to thereby change the orientation of the rotating lighting source.

Upon activation of the rotatable lighting source 002, the light produced by the rotatable lighting source 002 is projected ahead of the rider riding the bicycle 013. The rotatable lighting source 002 is oriented downwards to project light and illuminate the region nearer to the bicycle. Thus, to illuminate the region nearer to the bicycle, the rotatable lighting source 002 is rotated in anti-clockwise direction by the rotor 004. On the other hand, the rotatable lighting source 002 may be oriented upwards to project light and illuminate region farther away from the bicycle by rotating the rotatable lighting source 002 clockwise using the rotor 004. The rotor 004 rotates with same angle and same speed as the head moving up and down so that the light beam projection is always parallel to the eye seeing level of the rider.

In another example, the motion sensor 200 may detect the gesture of head of the rider moving sideways to the left or the right side. Based on the movement of the head detected by the motion sensor 200, the signal generator 011 generates a signal to then cause activation of either the left indicator light 007 a or the right indictor light 007 b. The signal generated by the signal generator 011 is received by the signal receiver 012. The signal received by the signal receiver 012 is then passed on the to the light control PCB module 005. The light control PCB module 005 then communicates with the left indicator light 007 a and the right indictor 007 b to then activate either the left indicator light 007 a or the right indictor 007 b. Upon activation, the left indicator light 007 a or the right indictor 007 b project light on the ground on the left or the right side of bicycle, thereby providing indication to the other commuters on the road about the intention of the rider of the bicycle of turning in either the left or the right direction, as well as illuminating the path for rider of the bicycle in the left or the right side. This further makes the riding experience more convenient and safer for the rider.

FIG. 19 illustrates various views of the bicycle 013 and the gestures produced by the head of the rider of the bicycle during the working of the left indicator light 007 a and the right indictor 007 b in accordance with the gestures detected by the motion sensor 200 of the head of the rider of the bicycle 013. As shown, as the head moves sideways to the left side, the signal generator 011 mounted on the helmet 014 generates a signal to then cause activation of the left indicator light 007 a. The signal generated by the signal generator 011 is received by the signal receiver 012, which is then passed to the light control PCB module 005. The light control PCB module 005 then communicates with the left indicator light 007 a to then activate the left indicator light 007 a. The left indicator light 007 a then projects light on the ground on the left side of bicycle to thereby provide turning indication and illuminating path for rider of the bicycle on the left side.
